This unit is supplied with a high temperature, all stainless-steel hose. It is very important to protect the integrity of this hose by not exceeding the bend radius of 2”. If a hose is subjected to excessive wear and tear, it will not be covered under warranty. Please inspect your hose and cover on a regular basis for any wear. Always remove the hose from the machine before winding the hose on the hose brackets to eliminate excess bending.
